ATTO RN EYS LOUIS J. BEMMELE, 0F NENARK, NEW JERSEY.

ROTARY BROOM 0R BILUSH.

Application filed September 26, 1918.

7 '0 all whom it may concern Be it known that I, Louis J. .RnMMELn, a citizen of the United States, and a, resident ofNewark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Rotary Brooms or Brushes, of which the following is a specification.

My invention relates to rotary brooms or brushes and more particularly to brooms or brushes used for street sweeping, track cleaning and the like.

The present invention is an improvement on my earlier Patent No. 743,195, granted Nov. 3, 1903.

An object of the present invention is to provide a brush of the type referred to which is simple and can be cheaply constructed and wherein the brush material and retaining, members are easily removed so as to provide for the easy and convenient replacement of brush material, such as reeds, ratan or the. like, by simple removal of the brush holding members without tak ing the brush apart.

Another object of the invention is the provision of stay or reinforcing members within the fold of the brush material which are likewise removable and which Serve to impart stiffness to the brush matcrial and to separate and hold the tufts or folds thereof in proper relative position.

()thcr objects of the invention will appear in connection with the follmving dcscription, and with the forcgroing and rclatcd objccts in View, my invention consists in the oleinents. parts, features of construction and combinations herein set forth and claimed.

In the drawiiug forming part of this specification I have shown one form of brush in which my invention may bc embodied.

in said drawing, Figure 1 is a pcrspmrtive view of one half of a brush head. Fig. '3 is a longitudinal sectional view taken substantially on the broken line 2-2, Fig. .1. Fig. 3 is an end view of a completed brush, and Fig. 4- is a fragmentary perspective view showing the relation of the holding ha r and the stay bar to the brush material.

The brush body preferably compriscs a series of disk-like members of substantially skeleton form which arc. spaced apart. and alined openings therein are provided. with lengthwise cxtenrling, mcml'icrs thcrcin con necting the skeleton-like disk members to Specification of Letters Patent.

Serial No. 255,775.

form substantially a cylindrical brush Body. The disk members may conveniently be made in halves and bolted together, with preferably square central openings formed between them to embrace blocks on the brush shaft.

For a sweeper brush of four feet in length, or thereabout, there may be three different types of disks; an end disk or head 10, an intermediate disk 11, preferably placed midway between the heads 10 and 12, and spacing disks 13. The disks 10, 11 and 12 may be provided with slots 14 for the reception of back boards 14; which serve to prevent the brush material 15 being pushed or forced inwardly to an undue extent, and all the disks 10, 11, 12 and 13 have alined openings 16 for the reception of preferably wooden bars 17 which are preferably secured tightly in place when the brush halves are constructed and which cannot be removed as thc wood swells quickly upon being exposed to moisture in use. The bars 17 may be secured in place in any desired way, however, and serve as separators for the sections of brush material.

An important feature of the present invention rcsidcs in lengthwise removal of the brush material holding members, which may he in the form of rods ,or tubes 18. Such mcmbcrs have a sliding fit in the alincd opcniugs 1f) arranged in all the disks and spaccd substantially midway betwccn the scparalor bars- 17. llcmovablc means for fastening l'hc brush holding members 18 in place arc provided, as. for cxample, cotter pins 20 may be iuscrtcd through openings .21 in slccvcs 2'. on the headers 10 and 12, providing cxicusious of the openings 1!) therein, and in holcs 23 provided in the rods, bars. tubes or the likc 18. 'lhcsc brush malcrial rclaiuiug members arc made of metal, as iron or stccl bars or pipe and. having a slidiup lit in the openings providcd therefor, may be rcadily rcmovcd by direct longitudinal movcmcnt. \Vhcrc wood or other similar uialcrial is used for brush retaining mcuus. it swells quickly upon cxposul'e to ihc \vcalhcr in the scvcrc use to which these hrushcs are put. and cannot be sul'iscqucntly rcuiovcd. ()rdiuarily itis sullicicnt to se curc thc brush material holdingmembers in place at one or two points only, and it is sullicicnt lo provide the heads ll) and 12 with the sleeves 23 and cotter pins 20, and such be done by hand, if desired, it is a feature sleeves need not-be provided eithe on the intern'iediate'disks 11 or the spacing disks 13.

Adjacent to the retaining members 18, and between the folds of the brush material 15, I provide stay orsti-fiener bars 24 which may be of wood but in such case are of suiiiciently reduced cross-section to bereadily inserted and removed longitudinally from the ali'ned openings provided for their reception in the several disks. Means are preferably provided for preventing their unin tentional or premature withdrawal, as, for example, nails 25 may be driven therein adjacent to the disks through which they pass, and may be pulled out when the stay bars are to be removed. The stay bars 24-, placed radially outside of the retaining members 18, are preferably somewhat wider than said members 18. They hold the folds of the folded over brush material apart at a proper distance and also, acting in conjunction with the separator bars 17, serve to keep the separate projecting tufts or rows of reeds, ratan or other brush material properly spaced from one another all the way around the brush- With the outer faces of the sep-' arator bars 17 and stay bars 24; arranged at substantially the same distance from the brush axis, as shown, the brush material is held up substantially stiilly and strongly to its work on both sides and with substantially equal tension or resisting power in both directions. By making the brush material retaining members of metal, as tubing, and the separate stay bars of wood, great strength is obtained without unnecessarily great weight.

To ut-brush material in place in the brush it is only necessary to forcibl insert the folded new brush material in p ace between the separator bars-'17 whereupon the holding members 18 may be inserted through the openings 19 provided therefor and passed through within the fold of the brush material and locked in place as by means of the cotter pins 20. Then the staybars 24 may be introduced in a similar manner. The

.same steps are performed in repairing worn brushes, but in such case it is, of course, necdone by direct longitudinal movement. The

old or worn brush material may then be.

readily removed and replaced by new ma 'teriall Withthe brush constructed as do scribed, the filling operations may be adyantageously carried out in a suitable filling machine, by means of which the folded over reeds are .forcibly pushed into place between the bars 17, 17 and held while the bars .18 are putin place. While filling may of great 'convenience and practical advantage to have the brush of such construction as to be well -adapted for machine filling,

my improved construction, as will appear from the foregoing.

I claim: 1. In a rotary brus a skeleton frame comprising a plurality of substantially parallel circular disk members spaced apart and: made up of part circular members remov-. ably secured together, lengthwise extending bars connecting said disks andforming sep arators for brush' material, folded over brush material between said separator bars, and cndwise removable brush material holding means inserted through alined o enings in the disks and passing through wit in the folded over parts of the brush material.

and various other advantages are secured by 2. In a rotary brush, a skeleton frame comprising a plurality of substantially parallel circular disk members spaced apart andmade up of part circular members removably secured together, lengthwise extending bars connecting said disks andforming separators for brush material, folded over brush material between said separator bars, I
